Abstract

The ignition of methane-oxygen mixtures highly diluted with argon was examined in the temperature range of 1516-1937 K behind a reflected shock wave. The ignition delay times were measured by monitoring pressure profiles and the total emissions at 5.0 cm from the end wall. It was found that the experimental result was correlated by the temperature and the concentrations of the gases. To complement the experiment, computer modeling study of methane oxidation was carried out using a GRI 1.2 mechanism.

메탄-산소를 아르곤으로 희석한 혼합기체의 점화 과정을 1516-1937K 온도 범위에서 반사 충격파를 이용하여 고찰하였다. 메탄 기체의 점화 지연 시간은 충격관 끝에서 5.0 cm 떨어진 곳에서의 압력 변화 및 광 방출을 측정하여 구하였으며, 각 혼합기체의 농도 의존도 및 온도 의존도에 관한 실험식을 구할 수 있었다. 메탄 산화 과정에 관한 실험 결과를 설명하기 위해 GRI 1.2 메카니즘을 이용한 컴퓨터 모의 실험을 수행하였다.
